According to the wiki, it's Tundra, Taiga, and Grasslands (which I'm pretty sure is sourced from SOPomo's SOSI AMA).

It says Deciduous Forests, not Grasslands.

At the time I wrote that (September) the most recent available source (the SOSI draft rules) showed Grasslands as being one of the biomes. This was changed sometime between SOSI, in mid-July, and the printing of the rules, in late August, to Deciduous Forests.

Does anyone have a good idea of how hard the div c computation aspect will be? Ex. Which formulas should we know? Regionals next week will be the first div c competition I have ever gone to and needless to say, Im terrified.

How in-depth should a normal Ecology test be on the biomes? I ask this because I've now done two tests, one at Regionals and one at States, where the test had very few questions about the specific biomes and those questions were very basic. My partner and I put a lot of information pertaining to the biomes on our reference sheet and we used next to none of it.

A third of the test should come from section two, theoretically. How in-depth is anyone's guess (as is typical for events this broad). Recall of obscure facts (like how "taiga" is Russian...total trivia) is not the makes of a good test, though.

Although, like Skink said, the rules state 1/3 of the test should draw from biomes, oftentimes this section is skimmed over. Usually, the biomes section just consists of identifying a biome by using a climate graph or listing the adaptations of organisms in the biome.
